+//! Benchmarking support
+//!
+//! Benchmarks are split up into two parts: the functions to be benchmarked live here, which the benchmarking code itself lives in `benches/bench.rs`.
+//! It's easier to write benchmarking code inside the main crate, where we have access to private items.
+//! However, it's easier to integrate with Cargo and criterion if benchmarks live in a separate crate.
+//!
+//! All benchmarks are defined as structs that implement either the [Benchmark] or [BenchmarkWithInput]
+
+pub mod client;
+pub mod ingest;
+
+/// Trait for simple benchmarks
+///
+/// This supports simple benchmarks that don't require any input.  Note: global setup can be done
+/// in the `new()` method for the struct.
+pub trait Benchmark {
+    /// Perform the operations that we're benchmarking.
+    fn benchmarked_code(&self);
+}
+
+/// Trait for benchmarks that require input
+///
+/// This will run using Criterion's `iter_batched` function.  Criterion will create a batch of
+/// inputs, then pass each one to benchmark.
+///
+/// This supports simple benchmarks that don't require any input.  Note: global setup can be done
+/// in the `new()` method for the struct.
+pub trait BenchmarkWithInput {
+    type Input;

+    /// Generate the input (this is not included in the benchmark time)
+    fn generate_input(&self) -> Self::Input;
+
+    /// Perform the operations that we're benchmarking.
+    fn benchmarked_code(&self, input: Self::Input);
